Sounds about what I would expect at this time of the year which is why I don’t even bother. As for seven gillers I’ve never caught one in timaru but I would expect they’d be around from about october onwards. Put your time into trying for other species like moki if they’re still around. Should be red cod around as well but it’s gonna be hard avoiding the carpet sharks and dogfish. Usually if you fish baits dropped straight down off the wharf you don’t get the sharks unless there’s a lot of really small doggies around. I’d say best time for fishing around there is december – march.
